Frequently Asked Questions
Will this fit without modification?
Yes, this stator is a direct plug-in replacement for the Honda CBR 600 F4i - no cutting or splicing is required.
What's included?
One replacement stator with its factory-length wiring and connector.
How do I know my stator has failed?
Weak or no charging, a battery that won't hold charge, or dim/flickering lights are common signs. Testing the wire-to-wire resistance against the 0.5 Ohms +/-20% spec above will confirm a fault.
Will the wire colours match my original loom?
The stator may use a different wire colour code to your original, but all wires are installed in the correct order, so match by connector position rather than colour.
